Like literally just search up the fandom you're interested in, then start following accounts you like and engage with their posts a lot. Because people of the same interests see each other's posts a lot, you'll eventually become more active in the fandom and naturally have people to talk to daily about stuff.
Well, anal fissure is just a medical terminology for a small tear or crack in the tissue lining of the anal canal. This can be caused by constipation, hard stools, child birth, or sometimes, anal penetration gone wrong. It's not something to be creepy about lol. We learn about this in anatomy and physiology classヾ(❀╹◡╹)ノ~
Given that I read a lot of BL and some BLs there is no proper prep and the Top just shoves it in, anal fissure is a good username, don't you think? XD

But I'm kinda lonely, and would appreciate any kind of online friends.
P.S, sorry if this is cringing you out
